Praggnanandhaa won with black pieces in 39 moves in a Tarrasch variation game early yesterday to halt Carlsen's run of three straight wins. The Indian GM lies in joint 12th spot after eight rounds with eight points.
Master Blaster Sachin Tendulkar congratulated R Praggnanandhaa on his win and wished him a long and successful career.
The teen grandmaster became only the third Indian to defeat Carlsen. He had a moderate run in the earlier rounds of the tournament, which included a solitary victory over Lev Aronian, two draws and four defeats.
He drew against Anish Giri and Quang Liem Le and lost to Eric Hansen, Ding Liren, Jan-Kryzstof Duda and Shakhriyar Mamedyarov.
Russia's Ian Nepomniachtchi, who lost the world championship match a few months ago to the Norwegian world no 1 Carlsen, is on top of the standings with 19 points followed by Ding Liren and Hansen (both on 15 points).
In the Airthings Masters, a 16-player online rapid tournament, a player gets three points for a win and one for a draw in the preliminary rounds. Seven more rounds remain in the preliminary phase.
